- Loop Control in Actuation

According to whether there is feedback, the actuation loop can be classified into two categories: open actuation loops and closed actuation loops. Open actuation loops refer to those in which there is no direct feedback from the outcome of the actuation, and the closed actuation loops refer to those with feedback. In Internet of Things (IoT), most loops belong to the closed actuation loops, in which the certain action to modify the contextual situations will repeat until the expected result is achieved.
